Wednesday afternoon update: Bush sits out practice

Reggie Bush is fine. Really.

But the Dolphins are being cautious and so he is not practicing today in the wake of Sunday's injury scare. Bush suffered a minor knee injury against the Jets but the team believed, and MRI tests confirmed, the injury should not keep Bush out a significant amount of time.

Bush will practice as soon as the swelling and stiffness are gone from his left knee. That could be by the end of this week. And if that happens, Bush might be able to play against Arizona on Sunday. The Dolphins don't expect Bush to miss more than one game at most, as I've reported previously.

With Bush out today, the Dolphins did a lot of work with Daniel Thomas and Lamar Miller. In that order. Still.

Despite evidence that Miller is the more explosive back and the fact the rookie is averaging 5.9 yards per carry to 3.6 yards per carry for Thomas, the second-year player remains ahead on the depth chart. Thomas would probably be the starter and get more carries if Bush cannot play.

Obviously, the issue remains whether Miller is capable of adequately protecting the passer on passing downs. He also could stand to learn the playbook better.

Linebacker Austin Spitler and defensive lineman Tony McDaniel also did not practice today.
